HEATING-FURNACE.

SPECIFICATION forming part of Letters Patent No. 438,887, dated October21, 1890.

Application filed June 14, 1890- Serial No. 355,486. (No model.)

To all whom it may concern:

Be it known that I, HENRY S. Houenroma citizen of the United States,residing at Goldbrook Sp rings, in the county of WVorcester and State ofMassachusetts, have invented certain new and useful Improvements inHeating- Furnaces; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

Thisinventionhas relation to improvements in heating-furnaces adaptedforburningwood; and the novelty will be fully understood from thefollowing description and claims, when taken in connection with theannexed drawings, in which- Figure l is a plan view of my improvedfurnace with the top removed. Fig. 2 is a transverse vertical sectionalview of the furnace, taken at the point indicated by the dotted line a:00 of Fig. 1. Fig. 3 is a front view with the hotair and smoke pipespartly broken away, and Fig. i is avertical longitudinal sectional viewtaken in the plane indicated by the dotted lines y y on Fig. 2.

Referring by letter to said drawings, A indicates a furnace,which issuitably constructed of brick or masonry and provided at the base of itsside walls with a number of coldair ducts a. This furnace has a topplate B, which is provided with a suitable number of apertures for theoutlet of the smoke and hotair pipes, as shown.

Suitably arranged within the casing or masonry is a horizontal cylinder0, having a door at its outer end through which wood, as fuel, may beplaced therein.

D D indicate radiating-cylinders. These. cylinders are arranged abovethe fire-cylinder 0 and parallel therewith, and are each connected withthe rear end of the fire or fuel cylinder by means of short obliquepipes at. These radiating-cylinders are connected at their opposite orforward ends by means of a transverse pipe E, and leading from the rearend of one of said cylinders is a smoke-pipe F.

The pipe a, which connects the radiatingcylinder bearing the smoke-pipewith the f uelcylinder, is provided with a damper b, the handle d ofwhich passes out through one of the side walls of the furnace, as shown,so as to allow it to be manipulated by an attendant. It will thus beseen that the hot air, smoke, and products of combustion may, by meansof the damper, be caused to pass through one of the radiating-cylindersand thence through the other before entering the smoke-pipe.

The forward ends of the radiatingcylinders are provided with removableheads, whereby access maybe had for cleaning them, and said heads areprovided with check-draft dampers, as shown. The masonry or housing forthese cylinders afford a hot-air chamber G, and the top plate B of thefurnace is provided with apertures bearing pipes H H,which may lead toany desired compartment in a building.

I I indicate diverting or deflecting plates. These plates, which aresecured at one edge to one of the inner walls of the furnace, extend theentire length thereof and overhang the radiating-cylinders in a curvedmanner. These plates are numerously perforated, as shown, and aredesigned to deflect the air-currents as they enter the ducts at the baseof the side walls, and without materially deflecting the draft will castthe cold or partlyheated air against said radiating-cylinders, andthereby absorb the heat therefrom before being finally discharged fromthe furnace.

With a furnace of the construction illustrated but little fuel isconsumed to attain a large amount of heat, the radiating cylinders anddeflectors being so arranged with relation to each other as tomaterially utilize the currents of cold air passing up from the bottomof the casing.

Having described my invention, what I claim is-- 1. In aheating-furnace, the combination, with the fire-cylinder, of theradiating-cylinders arranged above the same, and the perforateddeflectors overhanging the radiatingcylinders, substantially asspecified.

2. In a heating-furnace, the combination, with the fire-cylinder, of theradiating-cylinders arranged above the same, the obliquelyarranged pipesconnecting the rear ends of I ICO ing the radiating-cylinders with thefire-cylinders, and the curved perforated deflectors overhanging theradiating-cylinders, substantially as specified.

3. The combination,\vith the casing, of the fire-cylinder arrangedtherein, the radiatingcylinders arranged above the fire-cylinder andconnected with one end thereof by the oblique pipes, and the perforateddeflectors overhanging the radiating-cylinders, substantially as 10specified.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY S. HOUGI-ITON.
